i f ia rj fleetbr Gwhich s closed by a glass 7 111 6 W thin a: closurerim 8 which fits over conventional constructions I have provided an annular packingwifi .10. of as? bestos or other suitable packing material. The" usual prop brackets 11 and l2" are provided on the body v5 with the set screws 13;

14.. thereinfor securing thelampto the props on the vehicle to which it is attached. Within' the reflector is the lamp. bulb 15 which is located within adjustable connector 16 and which is operatedby adjustment screw 17 accessible from he rear of the body. 1

' ire'tgf edt 9 ei g e u to the body by means o a fastening suchas the bolt 22;; 18" provided? with alooped end 3W i h t. ndb y nd t e w rim n forc cooperation with the looped end .39,? PM 91 Of he es e 'i t tween its looped" end 24 and its opposite end 25 through which fastening bolt 22 passes, is V provide a"y;ielding: portion 26: Wliwh acts a pr n s the p dend -may oc cupy either the dotted. or full, line positions" shown in Fig. 3-. ;The part 19 ex- 7 tendsthrough an enlarged slot 27 in the sothat it has freedom of movement, when being moved from 'onefto the other of the positions shown Fig; 3. The above referred to portions A and B of my improved fastening, are preferably located at. diametrically;opposite points 'onthe lamp'body and closure rim as shown in Fig. l,'so that the glassof the lamp closurewill be helduniformly i -tension against thei-p'ackingring 10 of the reflector 6, and it will be seen upon reference to Fig. 5 that the looped end of part 18 is made in two sections 23 and 23", with the single section of loop 24 occupying the space between the sections of loop 23. The pintle pin 28 is adapted to occupy both sections of the loop 23 and the single section of loop;24c when the fastening is in operative condition. f

The operation of the parts 19 when they cooperate with parts 18 is to retain the closure glass 7 against the packing 7 ring with a yielding pressure which is sutficient to prevent relativemovement or v1-- bration between the parts, the spring portions 26 0f the members 19 operating to re-v tainv the parts in this yieldingly fastened V relation to one another. In order todetach forward into position to bringloops 24 into cooperative position with loops 23 wheneupon thepintle pins may be slipped within; 7

f sisting of a'rigid'membe secured to one of; said parts,v a spring member secured to the other of saidparts and 'normally extendingg the members 18 and19 of-each portion of order to release the pintel pin 28 for removal. fThis-operation be performed on'either side of the lamp so th'at the pintlepin of either one'of the portions Aand 'B may be removed ,in' order that thelosuremay be swung away from the lamp body upon-thatportion, the pintlepi'n of which has been left in position, thus permitting the other'portion to operate as "aJhinge upon which the closuremay be swung freely. I In stead of this manner of operating thefastening the closure may be completely removed by-removing both pintlepins in the manner above described. I

In replacing the" closure it is locatedfso that the sections of loops 23 of members 18 are opposite loops 24v of members 19. Thejspring portions 26 are then" pushed the loops andthe closure heldiniplace.

V It'will thusbe seen that-by means of my. improved fastening the closure, is held posi tively 'against rotative movement relatively to the body and reflector, and-simultaneously therewith isjheld yieldingly toward the with the glass in engagement withthe packing ring of the reflector. "This" feature is of advantage as compared with previous closure fastening devices in that although the door can not bedisplaced'rotatively with" relation to the body, the gla'ssis protected against excessive strains andbreakage'by having" the yielding pressure of spring :members' 19 exerted'upon the closure to hold the lass againstpacking ringIO.

Having thus described my invention what I claim 1s: j v

1. In combination with -a lamp body and closure therefor, a fasteningfor the closure consisting of a rigid member secured to one of said parts, a spring member secured to the otherof said parts and normally ex tending away from the rigid member, and

{means adapted; detachably"to connect the members 'w 7 toward the rigid member and intoengagement therewith: r

2. A fastening for vautomobile lamp closures, comprising in combination with a en:- the spring member is flexed body and a closure therefor, a looped rigid member secured'to the closure with the loop thereof extending beyond the closure, a looped spring member attached to. the body with the 1 00 thereof 'extending beyond the. body and away from, theQlOop of the rigid memberg and apin removably mounted in andadap'ted to'connect the loops when the spring member is fleXedto-bringthe loop thereof into cooperative I relation with the loop of the rigid member a closure for the body,a fastening comprismg a rigid inemberjsecured to' one of said parts, a: spring member securedito' another. of sa d parts away from the rigid member;
